2.0 About the O2 EII®
The O2 EII® Oxygen Analyser is designed to measure Oxygen levels in the range 0.1-100% O2
for tank oxygen level verification.
The O2 EII® is ergonomically designed, and equipped with several features to ensure ease of
use, and reliability. The instrument has been designed to be held in the left hand to enable
ease of use when checking your tank. It is fitted with a large digital display and operates from
an internal temperature compensated electrochemical oxygen sensor. Power is provided by a
9V battery which will last for approximately 1 year before replacement is necessary. The O2
EII® will automatically switch off after 10 minutes to ensure battery life is not compromised if
the instrument is accidentally turned on.
The O2 EII® is water and drop resistant. Designed specifically for the diving industry –
whether you may be a Sport (NITROX), Commercial or Military diver- where hostile
environmental conditions are the norm not the exception.
Your O2 EII® is supplied ready to use, all you need to do is push in the EII adapter.

3.0 Operation
3.1 Controls
The analyser is fitted with an ‘On’ button located on the side of the unit, when held in your
left hand the button should sit comfortably under your thumb. To turn the unit on press the
button once, the unit will automatically turn off 10 minutes after the button has been pressed,
as a result if the O2 EII® is accidentally turned on your battery will not be drained of power.
When it is switched on the analyser's display will show an oxygen reading do not use the O2
EII® before calibration (see Section 3.2).
Switch on
The ‘On’ button also acts as a hold button, to freeze the reading on the display press the ‘on’
button once. A ‘:’ symbol will appear to show the instrument is holding the reading. To
cancel the hold press the ‘on’ button once, the ‘:’ symbol will disappear and the instrument
will monitor ambient O2.
Reading held
Reading released
monitoring ambient O2
The low battery warning is a shown by ‘L’ on the display. When present, change the battery
before using the instrument (see Section 5.0, After Sales Service).
‘L’ low battery symbol
A waterproof calibration knob is located on the front. Turn it fully from left to right and then
fully left, the reading should increase and then decrease. (If the reading does not change see
Section 4.0, Quick Check).
WARNING
Do NOT use when
the LOW BATTERY symbol is on!

3.2
Air Calibration
WARNING
The analyser is sensitive to oxygen partial pressure. Calibration must always be carried
out at the same atmospheric pressure as oxygen measurement.
Air calibration is essential before every use and is performed as follows.
1.
Ensure that the sensor saver is not in place and that the EII adapter is fitted. The
adapter simply pushes into the sensor aperture.
2.
Expose the analyser to clean air for two minutes and adjust the calibration knob until
the display reads the correct value using the oxygen compensation chart (you can find
this chart on the inside of the back cover). If this is not possible refer to the note below
or to Sections 4.0, Quick Check and 5.0, After Sales Service.
Calibration
in clean air
The analyser is now ready for oxygen measurement.
Note: at very high altitude, it is possible that normal calibration is not achievable. For users
who intend to use the analyser at altitude, please refer to our web site for additional technical
information.

3.3
Checking your Tank
The Analox O2 EII® comes complete with a unique sampling dome which allows you to
directly apply the analyser to the outlet on your nitrox tank.
1.
Ensure the sensor saver is removed. Push the sampling dome into the sensor aperture.
2.
Ensure the Analox O2 EII® has been calibrated as per the instructions in Section 3.2.
3.
Very slowly open the pillar valve with your right hand until gas can just be heard
quietly hissing out.
Open the tank until the Nitrox is
heard gently hissing out
4.
Once the pillar valve has been opened and the nitrox is heard gently hissing, hold the
O2 EII® in your left hand and press the sampling dome firmly against the tank outlet.
Take a direct reading
from your tank
WARNING
Open tank valve EXTREMELY CAREFULLY
Before the O2 EII® is applied
5.
Close the pillar valve after fifteen seconds when a stable reading is observed on the O2
EII®.
Page 8
6.
7.
If in doubt repeat the procedure taking care to ensure a very low gas flow.
For ease of use when sampling several tanks, the O2 EII® is fitted with a hold feature.
Once a stable reading has been observed, press the on button to hold this reading. The
O2 EII® can then be moved away from the tank to enable you to record the O2 reading.
To cancel the reading press the on button once.
Reading held
8.
It is important to note that after a few seconds of the gas flow being stopped the
reading will begin to change towards the level in the surrounding air of 20.9% O2 you
should therefore take the reading or press the hold button while flow is ON.
WARNING
Very high flows may pressurise the sensor and
inaccurate readings or sensor damage will result.

Battery Replacement
a) Loosen the 4 screws located on the front cover. The gasket seal is designed to prevent
water leaking into the O2 EII® as a result the seal may be tight. Loosen the seal by
moving the lid from side to side, and then carefully lift the cover.
b) Slide the battery out of its holder and disconnect the lead.
c) Connect the lead to the new battery and slide the battery into its holder, under the
battery clip
d) Replace the cover carefully taking care that the sensor locates properly, and that you
do not trap any wires. Screw down until you feel the gasket tighten; do not over
tighten the screws.
5.2
Sensor Replacement
a) Replacement part number for your sensor is: 9100-9220-9B
b) Loosen the 4 screws located on the front cover. The gasket seal is designed to prevent
water leaking into the O2 EII® as a result the seal may be tight. Loosen the seal by
moving the lid from side to side, and then and carefully lift the cover.
c) Disconnect the connector from the back of the sensor.
d) Unscrew the sensor from the front cover.
e) Dispose of the old sensor according to local regulations for lead and potassium
hydroxide solution.
f) Remove the new sensor from its pack and check it for leaks, check the sensor has a
rubber o-ring fitted at the base of the thread on the front of the sensor. Screw the
sensor into the front cover tightly and connect to the EII connector. An arrow on the
back of the sensor shows where the connector should be fitted. Make sure the metal
prongs on the connector are facing the sensor and push in firmly.
g) Replace the cover carefully taking care that the sensor locates properly and that you do
not trap any wires. Screw down until you feel the gasket tighten; do not over tighten
the screws.
h) Push on the EII adapter.

5.3
General Care
Although designed to be water resistant the O2 EII® should not be intentionally immersed in
liquid or left outside unprotected.
The O2 EII® is built to resist the effects of day to day shocks and drops but remember it is a
precision oxygen analyser and should be looked after carefully to give long trouble free
service.
To clean the O2 EII® use a damp soft cloth.
Protect the O2 EII® from long periods of direct sunlight and do not subject it to high or low
temperature extremes.
The sensor in the O2 EII® is an electrochemical device and contains a caustic electrolyte.
Always check to make sure that it is not leaking and do not allow it onto any part of your
body or clothing. In the event that you do come into contact with the electrolyte wash the
contaminated part with copious amounts of water -see Section 6.0, Safety Information.

WARNING
If after handling the sensor your fingers or other
parts of your body feel slippery or stings wash
with a lot of water.
If stinging persists get medical attention!
Refer Section 6.0, Safety Information
5.4
Sensor Handling Information
O2 EII® oxygen sensors are normally supplied in sealed packs. Before the pack is opened
check that the sensor has not leaked. The sensors are themselves sealed and do not under
normal circumstances present a health hazard however if leakage of the potassium hydroxide
electrolyte has occurred use rubber gloves and wear chemical splash goggles to handle and
clean up. Rinse contaminated surfaces with water. If anybody comes into contact with the
electrolyte, please refer to Section 6.0, Safety Information.
Page 13
6.0 Safety Information
When the life of the battery has expired it should be disposed of safely in accordance with
local regulations.
When the life of the sensor has expired or it is leaking or otherwise damaged it must be
disposed of safely in accordance with local regulations.
The sensor contains KOH potassium hydroxide solution which is hazardous. In the event of
